  • Publication number: 20220131445
    Abstract: In a driving device according to the present invention, an internal space of a fixed housing provided with an electric motor and an electric circuit board configured to control drive of the electric motor is partitioned into a first chamber arranged therein with the electric motor and a second chamber arranged therein with the electric circuit board. The driving device includes a heat dissipation part configured to efficiently dissipate heat generated from the electric circuit board, from the second chamber to the outside of the fixed housing, and thus, heat generated from the electric motor is not easily transmitted to the second chamber via the fixed housing, and moisture is prevented from entering the fixed housing when outside air flows into the fixed housing.

  • Patent number: 10807458
    Abstract: An axle driving apparatus may include a first rotary shaft connected to an internal combustion engine; a second connected to an electric motor; a third rotary shaft connected to a driving shaft of a wheel; an interlocking unit interlocking the first, second, and third rotary shaft; and an input and output switchover unit. The interlocking unit and the input and output switchover unit are structured to switch the interlocking unit between a first mode in which only the power of the internal combustion engine is output from the third rotary shaft, a second mode in which only the power of the electric motor is output from the third rotary shaft, a third mode in which the power of the internal combustion engine and the power of the electric motor are combined and output from the third rotary shaft, and a fourth mode in which the power of the internal combustion engine is output from the second rotary shaft to the electric motor.

  • Patent number: 8312792
    Abstract: In a bi-directional overrunning clutched differential unit, a pair of coaxial hubs are relatively unrotatably fitted on respective coaxial output shafts, and are relatively rotatably inserted into a cage holding rollers. A pair of second bearings journal a clutch housing disposed around the cage is diametrically larger than a pair of first bearings journaling the respective hubs, and are disposed between the first bearings in the axial direction of the output shafts. An axial end portion of the cage and the second bearing on the same axial side are distant from the first bearing on the same axial side so as to have a space where a friction mechanism for applying a frictional rotation resistance onto the cage is disposed.
